Let's divide 201122 by 78
Let's see how many times 78 fits into 201122.

Advancing to step 1:
When dividing 2 by 78, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 78

On to step 2:
The number 78 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Fetch the next digit (1) from the dividend, attach it to 20 and continue: 201 / 78

Advancing to step 3:
If we divide 201 by 78, we get 2 and a remainder of 45.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 156 from 201, we get 45.
Take the next digit (1) from the dividend and append it to 45, then repeat: 451 / 78

Moving on to step 4:
The number 78 fits into 451 5 times, leaving a remainder of 61.
Write down 5 as next digit of the result. 
Result so far: 25.0
If we take 390 away from 451, we end up with 61.
Append the next digit (2) from the dividend to 61 and continue with: 612 / 78

Going ahead to step 5:
When dividing 612 by 78, we get 7 with a remainder of 66.
Use 7 as the next digit of our solution. 
Result so far: 257.0
The remainder is 66 after subtracting 546 from 612.
Fetch the next digit (2) from the dividend, attach it to 66 and continue: 662 / 78

On to step 6:
78 goes into 662 8 times with a remainder of 38.
The next digit of our result is 8. 
Result so far: 2578.0
The remainder is 38 after subtracting 624 from 662.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 7:
The number 78 fits into 380 4 times, leaving a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 2578.4
If we take 312 away from 380, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 8:
78 goes into 680 8 times with a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 2578.48
If we take 624 away from 680, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 9:
The number 78 fits into 560 7 times, leaving a remainder of 14.
The next digit of our result is 7. 
Result so far: 2578.487
If we take 546 away from 560, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 10:
If we divide 140 by 78, we get 1 and a remainder of 62.
Use 1 as the next digit of our solution. 
Result so far: 2578.4871
The remainder is 62 after subtracting 78 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 11:
The number 78 fits into 620 7 times, leaving a remainder of 74.
Use 7 as the next digit of our solution. 
Result so far: 2578.48717
Subtract 546 from 620 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 12:
740 divided by 78 is 9 with a remainder of 38.
Write down 9 as next digit of the result. 
Result so far: 2578.487179
Deduct 702 from 740 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 13:
When dividing 380 by 78, we get 4 with a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 2578.4871794
If we take 312 away from 380, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 14:
If we divide 680 by 78, we get 8 and a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 2578.48717948
Subtract 624 from 680 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

After the division, we end up with 2578.48717948 and a remainder of 5.6e-08.
